Cellular and molecular mechanism of memory storage

The goal of my laboratory is to study the molecular and cellular mechanisms, as well as the neuronal circuitry, underlying long-term synaptic plasticity, learning and memory. I believe that by studying the mechanisms underlying long-lasting synaptic plasticity and mnemonic processes we can generate corresponding insights into human cognitive disorders.

Our prior work established a critical role for translational control in long-lasting forms of synaptic plasticity and memory formation. Currently, our lab studies the molecular and cellular mechanism underlying long-lasting synaptic plasticity and memory. To study these processes, in a multidisciplinary approach, we combine transgenic manipulation, shRNA and miRNA delivery using lentiviral vectors, biochemical, imaging, behavioral and in vitro and in vivo neurophysiological methodologies.

In a complementary line of research, we intend to elucidate the mechanisms linking translational control with developmental disorders such as Autism and mental retardation and other neurological disorders such as Alzheimer’s disease.
